| 内容記述 | We introduce the preliminary results from the observation by fixed-point GPS simultaneous baseline determination network in Kanto-Tokai district, central Japan. Data of initial observation during 33 days (between 97 and 129 day of year, 1988) are analyzed. Satellite constellation was not good over Japan in this period and only one-sided four satellites in the NW direction are tracked. Excess path delays caused by troposphere are calculated using surface meteorological data. Residual zenith delay are also estimated at each site. Satellite orbit parameters are relaxed when more than four sites are tracked. The deviated satellite constellation caused the errors in baseline lengths estimation for NW-SE direction 2?3 times larger than those for the NE-SW direction. The standard deviations are less than 1 ppm for most of NE-SW directed baseline of 70 to 260 km lengths. Estimated zenith delay correction terms vary much more than the variation of the wet term excess pass delay expected in this season. The correction terms for satellite positions range 0 to 200 m, and are also much larger than the accuracy of the ephemerides used. Those improper estimates are probably caused by the errors of the position of the fiducial point of the network and the surface meteorological measure ments, although a part of the deviation could be attributed to the errors in the satellite ephemerides we used. ? 1989, The Geodetic Society of Japan.
